Does Your Disk Support Multibooting?

The following table shows the disk configurations on which you can install more than one operating system.
Disk configuration Requirements for multiple operating systems

Basic disk

This is the common name for the hard disk in your computer. You have a basic disk unless you have converted it to dynamic disk. MS-DOS and all Windows-based operating systems can access basic disks. A basic disk can contain up to four primary partitions. A partition is a section of the disk that functions as a separate unit. Each partition can have a different file format and different drive letter, for example, C: and D:. Each operating system must be on a separate partition.

Single dynamic disk

If you have one hard disk and you have converted it to dynamic disk, you can install only one operating system. You cannot multiboot.
To determine if you have a dynamic hard disk, click Start, click Control Panel, click Performance and Maintenance, click Administrative Tools.
Double-click Computer Management, and then click Disk Management. In the right pane, your disk will be labeled as a basic or dynamic type.

Multiple dynamic disks

If you have two or more hard disks installed in your computer, each dynamic disk can contain one installation of Windows XP Professional, or Windows 2000. No other operating systems can start from a dynamic disk. Windows XP Home Edition does not support dynamic disks.
